It seems like you're describing the characteristics of a high-pressure system. In meteorology, a high-pressure system is associated with clear, sunny skies and stable weather conditions. Here's an explanation of what happens in a high-pressure system:
-
Surface Air Movement: In a high-pressure system, the air at the surface is denser and tends to move outward from the center of the high-pressure area. This outward movement of air leads to a sinking motion, which suppresses cloud formation.
-
Sinking Air: The air above the high-pressure area descends towards the surface. As the air sinks, it warms up due to compression. This warming effect inhibits the formation of clouds because warmer air can hold more moisture, which reduces the likelihood of condensation and precipitation.
-
Clear Skies: As a result of the sinking air and the outward movement from the center, high-pressure systems are typically associated with clear skies and dry conditions. This is why they often bring sunny weather.
In summary, a big pressure system, or high-pressure area, leads to sunny, clear days due to the outward movement of surface air and the sinking of warm air that inhibits cloud formation.
